s Claims. (Cl.'206--60) This invention relates to a shingle package, andmore particularly to the packaging of self-sealing shingles, especiallyasphalt strip shingles of the square-butt type that have adhesivematerial applied in broken or continuous lines, dots, or other figures,extending lengthwise of the-shingles. on the weather surface. Theadhesive material is of suchnature and so positioned that when theshingles are applied to a roof and subjected to solar heat the butt orexposed portion of the shingles will be sealed or cemented down by theself-acting efiect of the adhesive.

Because of the adhesive material applied to the surface of the shingles,considerable difiiculty has heretofore been experienced in packing theshingles for shipment from the factory without causing them to becomesomewhat. deformed: while they are contained in the package, andconsequently interfering with proper and effective sealing when they areapplied on the roof.

The thickness of the adhesive material on the weather surface of eachshingle is slight, amounting usually only to about a few thousandths ofan inch. However, as in packaging a plurality of shingles are bundled ineach wrapper, the cumulative effect of the thickness of the adhesivematerial is considerable, being enough to cause the shingles to bend outof their normally flat condition. It is common practice in the industryto pack the shingles in bundles so that a given number of bundles willcontain the number of shingles required to cover a square, that is, tocover one hundred square feet of roof area.

It. is an object of'our'invention to provide a packagingfortransportation. of self-sealing shingles that will protect thecontents and avoid any objectionable bending or deformation of theshingles while inthe package.

Other advantages of the invention will appear from the followingdescription thereof, reference being had to the accompanying drawings,in which:

Fig. l is a perspective view of one form of the wrapper element of thepackage embodying the invention;

Fig. 2 is aperspective view of a panel or pallet for insertion in thepackage;

Fig. 3 is a perspective view of a modified form of the panel or pallet;

Fig. 4 is a plan view of a blank from which the wrapper element of thepackage may be formed, the blank in this instance having a continuousopening in the portion thereof that constitutes the bottom of thepackage;

Fig. 5 is a vertical view in section of the package and its contents,the latter being shown in phantom; and

Fig. 6 is a fragmentary perspective view of one form of self-sealingshingle to be bundled.

The fragmentary View of the shingle 10 illustrated in Fig. 6 is typicalof one form of self-sealing shingle that is to be contained in thepackage. In this form, the shingle has a series of substantiallyrectangular forms of adhesive material 11 applied lengthwise on theupper or weather surface in a predetermined arrangement and at aprescribed distance above the inner or upper ends of the cut-outs orslots 12 that define the side edges of the so-called square-tabs" of theshingle. In this instance, the

or rear surface to prevent the shingles from sticking to-v gether whenpacked or stacked one upon another.

While the adhesive material is preferably in the formof separatedrectangular figures, it may be applied in globules, in a continuousstrip, or in other forms. In some instances the parting stripe may beeliminated and in lieu thereof the face of the adhesive may be coveredwith anti-stick paper or other substance that can be easily stripped orpeeled olt when the shingles are to be laid or applied on a roof.

In Fig. 6, for the sake of illustration, the thickness of both theadhesive 11 and the parting stripe 13 is greatly exaggerated inrespectto that of the body of. the shingle. Usually the thickness of theadhesive is only a. few thousandths of an inch, about .020, and that ofthe parting stripe or material is negligible.

However, it is customary to pack the shinglesin bundles so that aspecified number of bundles will contain a sufiicient quantity ofshingles to cover a square of roof surface. Where the shingle bundleswere packed in the conventional manner, it was found that, as theshingles are flexible, the cumulative effect of the thickness of theadhesive caused the shingles to sag and become deformed, especially ifthey were kept packed for any length of time before being used.

Our improved packaging supports the shingles at intervals on pallets andcompensates for the increased thickopposed edges 18 of which are spacedapart. in the form of wrapper of Fig. l, the bottom has a series ofalined die-cut slots or openings 19 While in the form of Fig. 5, thebottom has a single continuous opening 2%.

The package, as seen in Fig. 5, includes a plurality of pallets orpanels 21 upon which stacks or catches of the shingles are supportedface up. The pallets 21' are formed of fiat rectangular sheets ofcorrugated board or the like. which are die-cut to provide a series ofslots or openings 22 or a continuous opening 23, which openingscorrespond substantially in position, size, and arrangement to those ofthe openings 19 or 20 of the wrapper and are positioned with relation tothe positioning of the adhesive 11 on the face of the shingles.

Each pallet 21 not only serves to support a given number of shingles soas to prevent them from bending but also, by reason of the slots oropenings therein, compensates for the increased thickness of thesupported shingles resulting from the application of adhesive on' theface of the shingles.

The openings 19, 20 and 22, 23 of the wrapper and the pallets,respectively, are preferably of such width as to accommodate theadhesive material 11 and the parting stripe 13. The spacing between theopposed edges of the flaps 17 is preferably of the same order as thewidth of the openings in the bottom of the wrapper and in the pallets.

In packing the shingles, the wrapper element is bent to shape and aspecified number of shingles are stacked face up on the bottom Wall ofthe wrapper. Other shingles, usually of the same number as thosesupported on the bottom of the wrapper, are supported on each of thepallets that are inserted in and form a part of the complete package.The package is then bound in the usual manner with round tie-Wires ormetal straps Z4.

We have found that double-faced corrugated board of the kind known inthe trade as A, B, or C flute, varying in thickness from A3" to may beused satisfactorily for making the wrapper and the pallets. However, wedo not limit use to these particular materials as other suitably strongand inexpensive materials may be employed.

Pallets of the form of Fig. 2 are preferred to those of the form of Fig.3, except where the adhesive is applied as a continuous strip, becausethe solid uncut portions between the openings in the pallet give itadditional strength, and afford additional support to the shinglesstacked thereon.

In packaging self sealing square-butt shingles having an overallmeasurement of 12" x 36", designed to be exposed five inches to theweather, they are usually packed in bundles, each containing abouttwenty-seven shingles, three such bundles being suflicient to cover asquare of roof area. In that case, two pallets are included in eachbundle or package, as indicated in Fig. 5, and the shingles in eachbundle are divided into three stacks of nine shingles each. Whereshingles of different dimensions and exposures are to be packed, feweror more shingles may be contained in each stack, and the number ofpallets used in each bundle, and the number of bundles required persquare, may be varied accordingly.

In storage and in shipping, a considerable number of packages ofshingles are piled one upon another. Where the shingles are packed inordinary cartons or wrappers, the weight of the pile effects a veryconsiderable pressure on the shingles. In the case of self sealingshingles having raised adhesive areas, that pressure is concentratedlargely on the high spots and tends to flatten the adhesive and/or tocause the shingles to stick together, particularly where they aresubjected in storage or shipment to conditions of high heat.

The slotted wrapper and pallets of our improved package overcome thesedifficulties by relieving pressure on the adhesive areas (whichconstitute only a relatively small portion of the whole shingle area),and distributing the pressure substantially uniformly over the rest ofthe area.

It is to be understood that modifications in the package as hereindescribed, and illustrated in the drawings, may be made within the scopeof the invention as set forth.
